’Tis observable, that at every leading of the treble the two hind bells dodg; and whensoever the _half-hunt_ dodgeth there, a _bob_ must then be made, except the _quarter-hunt_ dodgeth there with it, and then not; which is an infallible rule, by which he that rings the _half-hunt_ may always give notice of the _bobs_ as well when the peal is inverted, as in the ordinary way of ringing it. The _bobs_ fall out in course single and double, the one single, the next double; and so by turns; there being three single _bobs_ and three double _bobs_ in the _eighteenscore_, and consequently six of each in the 720. The aforesaid method being observed, will carry on the course of the peal to the end of _eighteenscore_, which is just half the 720, and then it terminates, as appears in the _eighteenscore_ here prickt: but by making an _extream_ that number may be doubled; for then _eighteenscore_ changes more will go in course according to the former method; and another _extream_ being likewise made at the end of the last _eighteenscore_ will compleat the 720. The manner of making an _extream_ I have shewed at large in the _Introduction_, _page 90._ where I have also set down a general rule for making them, to which I refer. The first _extream_ may be made either the first, second, or third time that the half and quarter _hunts_ dodg behind; or else at the first, second, or third single _bob_; at either of which places the _single_ must be made behind. 132546 │ 165432 │ 132465 │ 421536 │ 142563 _123456_│ _bob._ │ 134256 │ 412356 │ —————— 214365 │ 156423 │ 312465 │ 143265 │ 124653 241635 │ 514632 │ 321645 │ 142356 │ 126435 426153 │ 453126 │ 236154 │ _bob._ │ —————— 462513 │ 435216 │ 263514 │ —————— │ 162345 645231 │ 342561 │ 625341 │ 124536 │ 163254 654321 │ 324651 │ 652431 │ 125463 │ —————— 563412 │ 236415 │ 564213 │ —————— │ 136524 536142 │ 263145 │ 546123 │ 152643 │ 135642 351624 │ 621354 │ 451632 │ 156234 │ —————— 315264 │ 612534 │ 415362 │ —————— │ 153462 135264 │ 165243 │ 461235 │ 165324 │ _bob._ 312546 │ 162534 │ 143526 │ 163542 │ 135426 321456 │ 615243 │ _bob._ │ —————— │ —————— 234165 │ 651423 │ 134562 │ 136452 │ 153246 243615 │ 564132 │ 315426 │ 163425 │ 152364 426351 │ 546312 │ 351246 │ —————— │ —————— 462531 │ 453621 │ 532164 │ 136245 │ 125634 645213 │ 435261 │ 523614 │ 132654 │ 126543 654123 │ 546321 │ 256341 │ —————— │ —————— 561432 │ 342516 │ 265431 │ 123564 │ 162453 516342 │ 324156 │ 624513 │ 125346 │ 164235 153624 │ 231465 │ 642153 │ —————— │ —————— 156342 │ 213645 │ 416325 │ 152436 │ 146325 513624 │ 126354 │ 143652 │ 154263 │ _bob._
